春天与基于XML的配置基于注解的框架覆盖配置？ [英] Can spring framework override Annotation-based configuration with XML-based configuration?

问题描述

能否Spring框架为基础的注解覆盖配置与基于XML的配置？我需要改变它是通过注解已定义的bean的依赖，我不是bean的作者。

Can spring framework override Annotation-based configuration with XML-based configuration? I need to change a dependency of a bean which is already defined via annotations and i am not the author of the bean.

推荐答案

这应该没问题。一个Spring bean上下文允许您重新定义豆，用后来的定义压倒一切较早的。这应该适用于XML定义的豆类以及注释定义豆类，即便是混合。

This should be OK. A Spring bean context allows you to redefine beans, with "later" definitions overriding "earlier ones". This should apply to XML-defined beans as well as annotation-defined beans, even if they're mixed.

例如，如果您有

@Configuration
public class MyAnnotatedConfig {
   @Bean 
   public Object beanA() {
      ...
   }
}

---

<bean class="com.xyz.MyAnnotatedConfig"/>

<bean id="beanA" class="com.xyz.BeanA"/>

在这种情况下， beanA 的XML定义应该采取precedence。

In this case, the XML definition of beanA should take precedence.
